1 OIL PUMP TESTING EQUIPMENT SYNOPSIS OIL PUMP TESTER is equipment that is used to test the performance of the oil pump. In lubrication system of engine the oil pump plays a vital role. Serious damages are caused to the engine components when the pressure developed by the oil pump is low. Hence testing the oil pump becomes very important. To check the condition of the pump the actual performance of the pump is compared with the standard performance that is required for the efficient oil pump is measured at a constant pressure and at a rated RPM of the efficient oil pump is measured at a constant pressure and at a rated RPM of the pump. This quantity of oil is compared with the standard quantity of oil that should be delivered by the pump for efficient distribution of oil at the same pressure and RPM. If the quantity of the delivered oil is lesser than the standard quantity, it can be confirmed that the oil pump should be reconditioned or replaced. INTRODUCTION The purpose of oil pump is to circulate the oil under pressure to most of the working parts of the engine for lubrication. The main reason for using lubricant is to reduce as much as possible friction between two surfaces when in contact. The lubricant has the capacity to absorb the heat generated due to friction between the mating surfaces and transfer it to another region from where it can be released very easily. In engine the oil from the pump is transferred to the gallery. From gallery oil is pumped to the main bearings, crank pin journals, small and big end of connecting rods,

2 piston pin etc., since the oil is pumped to long distances through many passages sufficient oil pressure is necessary. The required pressure for most of the engine is Kpa. But this may also increase to 450 Kpa during certain conditions. The delivery oil at the pump shaft RPM of 600 at 3Kg/cm² should be 6 LPM. The pump maintains a fixed oil discharge quantity once the engine reduce or exceeds a specified speed, thus reduce torque losses when the parts preventing the pressure build up. So the oil pump must no be used in the engine without testing. Thus to test any type of oil pump the tester was designed and fabricated by us. WORKING PRINCIPLE The working principle of the oil pump tester is nothing but a comparison of the actual performance and standard performance of the pump. The principle employs the measurement of the actual quantity of the oil delivered by the pump and comparing it with the standard quantity of the oil delivered by a pump that is in a good working condition. The oil pressure in most of the engines is 170kpa to 240kpa. Under higher engine speed the pressure may go as high as 450 Kpa. For normal functioning of the lubrication system, when the speed of oil pump shaft is 600 RPM at an outlet pressure of 3Kg/cm² the quantity of oil delivered should be 6 LPM and at a constant outlet pressure of 3kg/cm² the oil delivered should be 43 LPM. In this tester, drive is given to the main shaft of the oil pump by a meter through drive housing. The pump can be made to rotate at 3 different speeds by means of a stepped cone pulley. The pump shaft is now made to rotate at a particular speed (say 600 rpm) by giving electric power to the motor. For example, to get a speed of 600 rpm, the belt is shifted to the lowest grooves in both the pulleys. The speed can be noted from the

3 mechanical tachometer that is fixed to the pump shaft by a dog drive. We can now find that the oil is being through the outlet pipe. During initial stage the gate valve is kept fully open. ADVANTAGES 1. Most of the engine components will be saved for serious damages. 2. It is most used all garages and industries. 3. It is a great boon to the people in the field of automobile engineering. 4. This tester is not only used to check oil pump in automobile but can also be used to check oil pumps in any other hydraulic system. 5. It can be used to issue fitness certificate of the new vehicle. DISADVANTAGES 1. Additional Cost is required 2. High maintenance cost. APPLICATIONS It is very much useful for hydraulic pump manufacturing industries. Thus it can be useful for the following industries; 1) Inspection Section 2) Oil Pump manufacturing industries-quality Control 3) All Hydraulic Components manufacturing Industries
